Here is the distribution of grades information for Test 1.

average = 31.10 out of 40 points. (77.7%)

Based on the measures above, you should use the following as a guideline for interpreting your grade:

Please take note: This distribution is merely a guideline. I do not record any letter grades for the tests. However, this scale is indicative of the quality of your work. A unique scale may arise for each of the tests. The final (overall) scale will include a weighted average of all the test distributions, appropriately adjusting the final scores.
